Method for concentrating subscribers in a local exchange

Abstract

Method for concentrating subscribers in a local exchange (LE), which comprises an exchange terminal ( 1 ), a V5 interface (V5) connected to the exchange terminal, a group switch ( 3 ) and an interconnecting line ( 4 ) between the exchange terminal and the group switch for connecting subscribers connected to the exchange terminal to the group switch. According to the invention, a number of V5 interfaces (V5) are connected to the exchange terminal ( 1 ) and the exchange terminal is connected to the group switch ( 3 ) via the interconnecting line ( 4 ), thus forming between the exchange terminal and the group switch an internal interface within the local exchange for concentrating V5 subscribers.

What is claimed is:  
     
       1. Method for concentrating subscribers in a local exchange (LE), which comprises an exchange terminal ( 1 ) , a V5 interface (V5) connected to the exchange terminal, a group switch ( 3 ) and an interconnecting line ( 4 ) between the exchange terminal and the group switch for connecting subscribers connected to the exchange terminal to the group switch, characterised in that a number of V5 interfaces (V5) are connected to the exchange terminal ( 1 ) and the exchange terminal is connected to the group switch ( 3 ) via the interconnecting line ( 4 ), thus forming between the exchange terminal and the group switch an internal interface within the local exchange for concentrating V5 subscribers. 
     
     
       2. Method as defined in  claim 1 , characterised in that a number of exchange terminals ( 1   1 ,  1   2 , . . . ,  1   n ) are incorporated in the same exchange terminal cassette ( 5 ) and the exchange terminal cassette is connected to the group switch ( 3 ) via the interconnecting line ( 4 ). 
     
     
       3. Method as defined in  claim 1 , characterised in that the exchange terminal ( 1 ) used is a V5.1 subscriber module controller ( 2 ). 
     
     
       4. Method as defined in  claim 1 , characterised in that, when a subscriber is being created, time slot data and/or V5 interface data regarding the V5 interface used by the subscriber is/are stored in a subscriber database. 
     
     
       5. Method as defined in  claim 1 , characterised in that, during call setup, a free time slot in the interconnecting line ( 3 ) is scanned and designated for the subscriber. 
     
     
       6. Method as defined in  claim 1 , characterised in that information regarding the time slot designated for the subscriber in the interconnecting line ( 3 ) and the time slot designated in the V5 interface is supplied to the exchange terminal to which the V5 interface used by the subscriber is connected. 
     
     
       7. Method as defined in  claim 1 , characterised in that the access node (AN) is connected via a V5 interface to the local exchange (LE). 
     
     
       8. Method as defined in  claim 1 , characterised in that a V5 interface is used that is a standard V5.1 interface or a standard V5.2 interface.
